SHADE ROLLER.

Application filed August 6, 1923. Serial No. 655,850.

To all 107mm it mag concern.-

Be it known that I, STEWART H. Hears HORN, a citizen of the United States, and a resident of Short Hills, county of Essex, and State of New Jersey, have invented a certain new and useful Shade Roller, of which the following is a specification;

The invention relates to shade rollersand more particularly to spring shade rollers which are arranged vertically instead of horizontally as in window shade rollers, but it is to be understood that the invention is not limited to such use and may be carried out in connection with any type ofdrum or roller on which a flexibleelement may be wound and unwound.

The object of the invention is to produce a tubular roller of great strength and at a low cost.

A further object is to provide means, other than the material of the flexible element, for supporting the same on the roller.

A further object is to provide means whereby the flexible element will not be injured or destroyed by accidental removal from the roller.

These and further objects will more fully appear in the following specification and accompanying drawings considered together or separately.

One embodiment of the invention is illustrated in the accompanying drawings, in

which like parts in all of the several fig-1 ures are designated by corresponding characters of reference, and 111 which- Fig. 1 is a side elevation, partly broken away, of a spring roller embodying the invention.

Fig. 2 is a fragmentary side elevation of a curtain or shade.

Fig. 3 is an end elevation of the roller.

Fig. 4 is a similar view viewed from the opposite end, and

Fig. 5 is a transverse section of a roller with the curtain or-shadeelement in position. g a

In the embodiment of the invention illustrated in the. drawings, the invention is shove a applied-t a ve t a ly a ran d roller, for use in bridging the bellows of railroad car vestibules.

The roller 1 is illustrated as a sheet metal cylinder with a groove 2 extending longiis not a cylinder its longitudinal edges will be spaced apart forming a gap extending the length of the lining. The lining may be squeezed to reduce its more or less cylindrical diameter to somewhat less than that of the bore of the tube 1; it may then be inserted in the tube, the grooved portion of the latter lying in the gap between the longitudinal edges of the reinforcing lining. The elasticity of the lining-v will cause the same to tightly engage within the bore of the ,tube.

Secured in any suitable manner at one end of the tube 1 is a cap 4 having a cen tral opening which forms a bearing for a spear 5 of rectangular cross section. The cap 4 is provided with a notch 6 in line with the groove 2.

The opposite end of thetube 1 is enclosed by means of a cap? notched as is the cap 4, but completely encloses its end of the tube. The cap 7 carries the usual pintle 8, and is provided with an annular rim 7.

In connection with the roller 1 above described is employed a screen 9 of heavy cloth. One vertical edge of the screen is hemmed to form a pocket, in which is inserted a stout wire rod 10. The rod is of greater length than the screen and one end projects below the-bottom thereof.

The. opposite vertical side edge of the screen is to form a pocket within The cap 7 is not which is disposed a batten 11, and to the center of the batten is secured a loop 12 which cooperates with a hook or shackle (not shown) for securing the screen in extended position. 7

In operation the screen is made up with the rod 10, batten 11 and fixture 12 in position. The rod 10 may besecured against longitudinal movement in any desired manner.

The projecting end13 of the rod is seated in the cup of the cap 7 in line with the ried on or near the plattorinof a car, and

the spear 5 is inserted in a rectangular opeir ingflina bracket on or near the roof or the same platform. hen two cars are coupled together the free edge ofithe screen carryingthe batten 11 is pulledyacross the space between the adjacentplatrorms of the cars, and the loop- 12'is secured to a shackleon the other platform.

The unwinding of the screen will wind thespring 14 or the roller 1 and the screen will'remain taut notwithstanding any move-- ments of the cars relatively to each other."

When the 'cars'are uncoupled the loop 12 will be cast off the shackle,and the screen will be automatically wound upon the roller 1 by means of the spring l l. Should the attendant fail to cast oil? the loop lQ, or

should the cars become uncoupled accidently duringtransit, the loop 12 w'ilbremain fast to the. shackle, and as't he :oars part, the screen will be unwound from the irolleriand' the rod 10 will be pullcdfrom the slot 2 without destroying the screen.

The invention may be employed in conneotion with window shade rollers to-pre vent tearing the. shade if pulled down'to'o far, it a being. understood that: when used as:

a window shade roller, the oap'4: will carry the usual pawls adaptedto cooperate with a locking notch carried by the spear 5;

Thelining S will reinforce the tube '1 and is unsecured thereto except by means of its own elasticity; The walls of the groove 2 lying in thegap between the edges ot'the lini-ng, will prevent the lining from turningrelatively to the. tube 1.

In accordance with the provisions of the patent statutes the .prinI'cipIe' Of the inventi on has 1 been described, together with the apparatus which is now considered to represent the best embodiment thereof, but it is desired to have it understood that the apparatus shown is merely illustrative, and that the invention may be carried out in other ways.

The invention having been'described what is claimed as new and desiredto be secured by Letters Patent of the United States, is

1. A device of the a character described,

. comprising a vertically ;ar-ra-ngedcylindrical member, there being a longitudinal-groove in the surface of the member, said groove be ing of less length than the member whereby a wall is formed at 'one end or the groove, and an element carried in the groove, said element engaging the walliwhereby the element will be"supported thereby, the Width of the groove being greater than the lateral dimension of thejelement."

2. Adevice of the character desoribedy compris nga vertically arranged cylindrical member, there being-a longitudlnal-groove-.

in the surface of the member, said groove being of lesslengththan the'member whereby a wall-is formed at the lower end of the groove, andanelement carried in and extending longitudinally of the groove, one end for "said element engaging I the wall whereby the 1 element -will be supported thereby, the width or the groove-being greater than the diameter ofthe element.

3. A device of the character"described,

comprising a vertically arranged cylindricalmember, there being a longitudinal in the surface' of the member, said being of less length than the member where by a wall is "formed at the lower end ofthe groove a rodcarr-ied in and extending longroove gitudiiially ofthe'gr'oove, said rodresting onthe wall whereby the rod will-be supported thereby, and a flexible sheet secured by one j edge thereof to the =rod,"the"width of the groove being gre'ater*tl1an the-diameter of the rod'L- 4. A device of the character' 'desc'ribed, comprising a vertically arranged cylindrical tubular member, there being a groove tto'rmed in theouter surface of-thomem'ber and extending;longitudinally thereof, the member beingenclosedby a cap at the lower end thereof, said cap forming a wall at the lower end ofthe -g'roove, a rod resting within the groove and extending longitudinally thereof, oiie end-ot said rod engaging said p flexible sheet 'securedto therod, the width of thegroove being greater than thediameter of the rod. M

1 '5. A de'vic'efof the character described,

comprising a vertically-arranged cylindrical tubular member, there being a groove formed in the outer surface of the member and extendi'i'iglongitudinally thereof, the member berng enc'lo'sed by a *atone end thereof? groove and being supported"thereby,= and a Said cup forming a Wall at that end of the groove, a rod resting in the groove and eX- tendinglongitudinally thereof, said rod being of less diameter than the Width of the groove, and a flexible sheet secured to the rod, said sheet having a pocket in which the rod lies, the ends of the rod projecting from said pocket, said rod resting on the cap to support the rod, the rod being retained in the groove by Winding the sheet around the 10 member.

This specification signed this 3rd day of August, 1923.
